+> [!WARNING]
+> 因为该方法自 Chrome 33 起被弃用，该 API 在 Firefox 中并未被实现。请改用 [runtime.onMessage](/zh-CN/docs/Mozilla/Add-ons/WebExtensions/API/runtime/onMessage)。
+
+当从扩展进程或内容脚本发送请求时触发。
+
+## 语法
+
+```js-nolint
+chrome.extension.onRequest.addListener(function(
+  request,         // 可选的任意类型
+  sender,          // runtime.MessageSender
+  () => {/* … */}  // 函数
+) {/* … */})
+chrome.extension.onRequest.removeListener(listener)
+chrome.extension.onRequest.hasListener(listener)
+```
+
+事件有三个函数：
+
+- `addListener(listener)`
+  - : 添加一个该事件的监听器。
+- `removeListener(listener)`
+  - : 停止监听该事件。`listener` 参数是要移除的监听器。
+- `hasListener(listener)`
+  - : 检查 `listener` 是否注册到该事件上。若该监听器正在监听该事件则返回 `true`，否则返回 `false`。
+
+## addListener 语法
+
+### 参数
+
+- `listener`
+
+  - : 当此事件发生时调用的函数。该函数传递以下参数：
+
+    - `request`
+      - : `any`。由调用脚本发送的请求。
+    - `sender`
+      - : {{WebExtAPIRef('runtime.MessageSender')}}。
+    - `sendResponse`
+      - : `function`。当你有响应时调用的函数。参数应为任何可 JSON 化的对象（如果没有响应则为 undefined）。如果在同一文档中有多个 `onRequest` 监听器，则只有一个可以发送响应。

+> 此 API 基于 Chromium 的 [`chrome.extension`](https://developer.chrome.com/docs/extensions/reference/api/extension/#event-onRequest) API。该文档衍生自 Chromium 代码中的 [`extension.json`](https://chromium.googlesource.com/chromium/src/+/master/chrome/common/extensions/api/extension.json)。
